Show that the set of all bit strings (strings of 0's and 1's) is countable. Let B be the set of all bit strings. Showing that B is countable requires finding a function f from Z+ to B that satisfies certain properties. Which of the following properties are needed? (Select all that apply.) Ofis one-to-one fis transitive fis onto Ofis symmetric Ofis reflexive Of is a well-defined function from Z+ to B X

Show that the set of all bit strings (strings of 0's and 1's) is countable. Let B be the set of all bit strings. Showing that B is countable requires finding a function f from Z† to B that satisfies certain properties. Which of the following properties are needed? (Select all that apply.) f is one-to-one f is transitive f is onto f is symmetric f is reflexive f is a well-defined function from Z+ to B BX Each of the following formulas defines a function from Z to Z. Which functions are one-to-one but not onto? (Select all that apply.) ☐ h(n) = 8n² for each integer n | g(n) = 4n — 8 for each integer n f(n) = 3n for each integer n = 3 for each integer n O q(n)
